1919 Clemence

1919 Clemence, provisional designation 1971 SA, is an inner main-belt asteroid discovered on September 16, 1971 by J. Gibson and Carlos Ulrrico Cesco at Leoncito Astronomical Complex, Argentina.

Photometric measurements of the X-type asteroid made in 2005 at the Palmer Divide Observatory showed a light curve with a period of 7001685000000000000♠68.5±0.1 hours and a brightness variation of 6999600000000000000♠0.60±0.03 in magnitude. Czech astronomer Petr Pravec from the Ondřejov Observatory believes this may be a tumbling asteroid.

It is named for American astronomer Gerald Maurice Clemence (1908–1974), first scientific director of the United States Naval Observatory and professor of astronomy at the Yale Observatory, known for his work on the theory of the motion of Mars, and other contributions in celestial mechanics, notably on the motion of Mercury and on the system of astronomical constants. He served as president of the American Astronomical Society and of IAU.
